now In UE5.2 I’ve encountered the same problem but not completely the same, in my project, i can normally run developmenteditor or development from VS, and i can normally cook and pakage my project and i can normally run the pakaged program. what casue this kind of “failed to find shader map for default material WorldGridMaterial” is running shipping from VS, this is my specific kind: “LowLevelFatalError [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\Materials\MaterialShared.cpp] [Line: 2713] Failed to find shader map for default material WorldGridMaterial(/Engine/EngineMaterials/WorldGridMaterial.WorldGridMaterial)! Please make sure cooking was successful (No inline shaders, null GTSM)”. I tried something like type “recompileshaders all” in console. I got some info like project setting generate chunk enabled may casue this problem from other posts. But my project need that genertate chunk on.
